Decanuclear FeIII clusters with hemiacetal ligands: a new {M10(μ3-O)8} cluster core.

The characterization of a decanuclear FeIII cluster with α-methyl-2-pyridinemethanolate, generated by the hydrolysis of Schiff bases, inspired us to carry out an initial exploration of the direct syntheses of medium nuclearity FeIII clusters starting from aldehydes in methanolic medium. The new complexes exhibit an unprecedented {Fe10(μ3-O)8} cluster core.
